SAFETY DEVICE FOR OCCUPANTS OF VEHICLES;

Specification of Letters Patent.

Patented July 21, 1908.

Application flied March 16, 1908. Serial No. 421,526.

Be it known that I, RICHARD RADTKE, royal forestry steward, subject of"the German ,Em eror, residin at Suhl, Kingdom of Prussia, erman Em ire,have invented certain new and useful mprovements in or Relating to SafetDevices for the'Use of Occupants of Vehic es, of which the following isa specification.

My invention relates to a safetydevice for the occupants of vehicles,the object of which is to revent such occupants of a motor vehicle orexample from being thrown upwards and forwards' in the case of a suddenshock, owing to the. momentum of the car or their own weight and thusinjured by falling head downwards.

The action of the device is such that it doesnot in any way interferewith the free movements of the person using the same such as the driverand when the vehicle experiences a sudden shock the driver or otheroccupant is elastically held at theshoulders in such manner that he isslightl thrown upwards and forwards, but after t e absor tion of themomentum of the body, pulled ack again, in a springy manner to his seat.In that way he is protected from injury in case of such accidents.

According to this invention, the protecting device consists of tworubber holders orbands which are elastic in themselves, and which areplaced round the body of the erson in such manner that they rest securey on the shoulders and are connected together by means of a back strapand of an easily detachable breast strap, that is to say they cannotfall off from the shoulders, and nevertheless insure an ease of movementof the wearer; and of two vertically expanding springs secured to or atthe seat and connected to the rubber holders by means of easilydetachable hooks. In the case of a sudden shock to the vehicle,- therubber holders and the springs expand, absorb the momentum and pull thewearer back to the seat ,with a vertical pulli -In order that the wearershould not always springs in the seat by means of easily detachle springhooks, and on the other hand,

the breast strap is rendered easily detachable v 'waistof t e wearer.

by means of hooks and chain so that the wearer can at once pull off thedevice.

The safety device according to this invention is illustrated by way ofexample in the accompanying drawing.

The elical springs dare mounted in the seat of the vehicle and providedwith eyes at the top and at the bottom. With the bottom eye engages ascrew bolt, 1) passing through the bottom of the seat and secured athere by means of a nut c with a metal' washer. The springs aaresurrounded by metal sleeves d which are closed at the top by means ofacover e secured below the upper eye to the s ring. The cover isprovided at the bottom ace with a leather or rubber plate f for thepurpose of avoiding noise in driving. The springs a could be arranged,if the space in the seat box is insufficient, outside the same as shownfor; the spring a.

.In that case there is arranged under the bot- By means of a devicewhich will be now described, the rubber bands or bolts are arranged insuch manner that they rest'firmly on the shoulders and in spite oft-hat,can be easily stripped off.

To the-rubber belts or straps k are sewed I from the shoulders downwardsstraps ({n which form loops. Through the loops m is drawn the backtransverse strap n the ends 100 of which can'be brought nearer togetheror further a art,'accor d1ng to the size of the Owin to tlfe arrangementof the-loops mthe evel according, to the height of the wearer. On thefront side the two rubber holders-or bands 7c are connected-together bythe belt p, sewed 'onto the right holder or band and, provided at itsfree end a chain g which] 10 Figure 1 shows the springs in the seat in rof the rubber holders or bands 7c,

ack connecting 3 part a can besecured at ahigher or lower. 1-95 Iholding the body, the straps are prevented from pressing too hardthereon in case of an accident. Owing to these rubber stra s k and thesprings a, the pull which-brings ack the wearer, is an elastic one.

What I claim is:

A safety device for the occupants of vehicles comprising in combinationa pluralit of rubber stra s forming a closed belt, held on the shoul ersin an easily detachable manner by loops and back straps rovided with abuckle, as wellas of a breast and attached at one side and connected atthe attache b other side b means of hooks and chain in an easily detacable manner, two vertical helical springs beingarranged on the seat, tothe upper e es of which the rubber straps are means of easily 0 ened'spl'ing hooks so tat the springs an the rubber straps exercise anelasticvertical 1111 on the body of the wearer when it is t own upwardsand forwards by the vehicle striking an obstacle, in such manner thatthe said wearer is ulled'back to the seat.

testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
